INSPECTION AND MAINTENANCE
9
9-11
Check if the alarm occurs immediately after
the power is turned on.
Cause and remedy for overvoltage
no
yes
Internal elements may be broken.
Contact us.
Reduce the power supply rating to within the
specification value (rated voltage -15 to +10%).
yes
yes
Check if an external regenerative resistor is
connected.
Connect an external regenerative resistor.
no
Measure the resistance of the regenerative
resistor.
Check if the measurement is as shown in
table 2.
no
A poorly caulked connector or a broken wire in the
resistor is probable. If a broken wire in the resistor is
the cause, contact us.
Check if the power factor improving
equipment is used.
no
Examine adoption of power coordination reactor.
Contact us for details.
yes
[Indication on 7-segment LED]
4. Overvoltage
[Cause and remedy]
[Description of trouble]
The DC voltage inside the servo amplifier exceeds the rating,
possibly causing breakage.
Check if an external force functions to rotate.
(Such as in vertical application)
Cause and remedy for overspeed
Check if the trouble is eliminated.
Contact us.
Change the structure of the machine.
yes
The setting of the response frequency has been too
small to cause overshoot, resulting in overspeed.
yes
no
Increase the setting of parameter No. 7
(auto tuning gain).
[Indication on 7-segment LED]
[Cause and remedy]
[Description of trouble]
The speed of the servomotor exceeds the rating, possibly
causing breakage.
Connect U with U, V with V and W with W.
Check if the U, V and W cables are
connected correctly between the servo
amplifier and servomotor.
no
no
yes
3. Overspeed
Target
value
Actual speed
Overshoot
Extend the acceleration time so that the peak torque
is not limited.
Use the monitor mode at the keypad panel
to monitor the peak torque. Check if the
peak torque during acceleration is limited to
the setting of parameter No. 23 (max.
current limit).
yes
no
